IMPBQVEMENT IN HARROWS.

The Schedule referred to in these'Lettex-s Patent and making part 'ot the name.

To all whom it may concern Be it known that "I, DAVID L. J AQUEs, of Hud- Ason', in the county of Lenawee and State of Michigan, have invented a new and valuable Improvement 'in Harrows; and I do hereby declare that the follow- Ving is a full, clear, and exact description of the construction and operation of the same, reference being' had to the annexed drawing making a part of this specification, and to the letters and gures of reference-marked thereon. y

yIiigure l of the drawing is a top viewof my invention.

l1gure2 is a view of the inner side of one section of my barrow. A Y

My invention relates to narrows; and consists mainly-in theconstruction and novel arrangement of devices designed to guide the harrow with certainty, and to provide a ine'ans for adjusting all of the teeth of the ha'rl'ow to an y; desired inclination.

The letter A of the drawing designatesvthe llarrowframe, formed in two sections, pivoted together at cach end.

.B B represent, the rotary adjustable bars, whichbear the teeth of thel barrow.' .These bars are formed with journals adapted to fit in seats made in the long side-bars ot' the frauie, in snch a. manner that,` while the outer ends' of t-he bars have their journals working in circular mortises cut partly through the frame-bar, the inner journals are fitted into circular notches eut from the under sides ofthe inner frame-bars, and are kept in place by strips a a, of metal, secured to the under side of the frame-bar.

At or near the inner ends of the adjustable rakebars are fastened thereto the rigid arms b b, which are lpdvoted to the long connecting-bars c c in such a manner'that all of the rake-bars in each sectional barrow will be connected, and have the same angular 'posi- JOTI, l Y 'v A o The arm b', attached to the rear rake-baryis made somewhat longer than the others, and pivoted toit is the,paw1 e, arranged to engage with a ratchet, 2,011

Lthe upper surface of the frame-bar, thus securing the rake-bars in any desired position. Y -l lt is apparent that'the inclination of the teeth of the barrow may in this manner be regulated at will toA l suit the nature'ot` the soil. Or, when the teeth are -operating, they may be inclined to thercar, thus facilitatingitsmovement overgrass or hard ground. l

D represents a combined' guide-blade and runner attached to the inner end of the rear lrake-bar of each sectional harrow, and adapted, when the teet'h thereof are set up, to strike into the ground deeply with its point, thereby serving to keepv the barrow in a certain path and prevent swerving from side to side.

/Whenthe teeth are laid down to facilitate draft,

.the point of the guide'D isturnedto ther rear, and it becomes a supporting runner for the barrow.

'What I claim as my invention, and desire to se- 'eure by Letters Patent, isj In a folding hal-row, the arrangement ofthe trans.- verse rotary tooth-bearing vbars B, the connecting-- bar c,pa\vl efaud ratchet 2, and the -combined/runner and guide-blade D, substantially as shown and described.

' In testimony that I .claim the above, I'have hereunto subscribed my name inthe presenceof two wit- `nesses.
